JOHN WVOOK, OF CANTON, OHIO, ASSIGNOR OF ONE-HALF TO JOHN C. SKELTON ANDALBERT HOEFFER, BOTH OF SAME PLACE.

PUMP.

SPECIFICATION forming part of Letters Patent No. 320,737, dated June 23,1885. Application filed July 26, 1884. (No moan.)

To all whom it may concern:

Be it known that 1, JOHN NVOCK, a citizen of the United States, residingat Canton, in the county of Stark and State of Ohio, have inventedcertain new and useful Improvements in Pumps and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon, in which- Figure 1 is a side elevation. Fig. 2is a sideelevation showing pump in section. Fig. 3 is an end view of the lowerportion or bottom of the large tube or pipe. Fig. 4 is a bottom view ofthe inside tube, and Fig. 5 is a transverse section of the pump.

The present invention has relation to the general improvement in pumps;and it consists in the construction and combination hereinafterparticularly described and claimed.

Similar letters of reference indicate corresponding parts in thedrawings.

In the accompanying drawings, A represents the large tube or body of thepump proper, which is substantially of the form shown in the drawings,the bottom or lower end of which is provided with the openings a and thevalve B. Said valve may be of the form shown in the drawings, or anyother desired form. A close union will be made between the top of thetube A and the hollow piston D, so as to make the connection at suchpoint perfectly water-tight by means of a cap, 0, fitted about thepiston D, so that the latter may slide therein, and formed of a circularband of larger diameter than the tube A with lugs c on its inside andhaving a converging top within which is any suitable packing, 0 0 asshown. The lugs c of the cap will engage or interlock with the beveledor inclined ilangcs 0, formed on a collar, 0, secured to the upper endof tube A. By passing the lugs a between the ends of flanges c and thenturning the cap 0, the latter will be drawn down tight upon the tube Aand the packing composed by the converging top of the cap, so that aclose union. will be effected between the tube and hollow piston andwater prevented from escaping.

\Vithin the tube A is located the hollow piston D, which issubstantially of the form shownin the drawings, the bottom or lower endof which is provided with the valve d,

which may be of the form shown in the drawk ings, or of any otherdesired form. The bottom or lower'end of this hollow piston is providedwith the packing E, which is to fill the tube A, as seen in Fig. 2. Justabove the packing E is located the vent F, which permits the water topass between the hollow piston and tube A, so as to flow out through thespout A Any desired number of these vents may be used. This hollowpiston is formed airtight at its top, so as to form an airchamber withinsaid hollow piston, thereby causing the pump proper to throw acontinuousstream after it has been properly filled.

It will be seen that by an upward movement of the hollow piston the tubeA will be filled by means of the suction caused by the packing E, andthat by a downward movement of said hollow piston it will befilled fromthe water in the tube A, when an upward movement will again fill thetube A and also carry up the water within the hollow piston D, when adownward movement will fill the tube A above the packing E, therebycausing the pump proper to throw a continuous stream. It will also beseen that by my peculiar arrangement I am enabled to form a valve-seat,an air-chamber, and also the operating-rod in a single piece or tube.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

In a liitpump, the combination of the pump barrel A, having at its upperend the inclined flanges c, the hollow valved plunger D, work ing withinbarrel A, the cap 0, fitted about plunger D and formed of a band largerin diameter than tube A, and having lugs c on its inside, and a topconverging from it to the plunger D and a packing in the converging top,as shown, for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein presence of two witnesses.
